Exercise?

I'm new to this forum. I wondered if people are really sticking to the low salt diet. It is hard. I have been doing pretty well but have been eating chocolate for the last several days. And I think it has caught up with me. I know I am getting an episode when my jaw feels tense and tight, And I start sweating a lot and have a little hard time swallowing. It always happens always in the morning. Any thoughts on other people's symptoms and how to keep from getting it in the morning.
